No matter how many hours you ever The Citadel with, you will be a knob your first year, and an academic freshmen. After that year you will be whatever academic classification that you actually are.
As for the accepted transfer credits, make sure to call the registrar's office. They're incredibly busy right now, with one of the largest classes in school history matriculating, so they could have made a mistake. If some of the classes you took are not offered at The Citadel, then you might not get credit. But it's worth it to ask. I took an Arabic course through joint enrollment and got a general elective credit even though Arabic is not offered at The Citadel.
